Commit Message

Instead of allocating a fake IOMMU domain for all Exynos DRM components,
simply reuse the default IOMMU domain of the already selected DMA device.
This allows some design changes in IOMMU framework without breaking IOMMU
support in Exynos DRM.

Inki:
If possible, please consider this patch as a fix for v4.19-rc, this will
help doing a rework in IOMMU and DMA-IOMMU frameworks in v4.20 without
breaking Exynos DRM. It worked for current IOMMU code, but such usage is
considered as a hack.
